Former President George W. Bush said Friday that he is "not a fan" of Syrian President Bashar al Assad, but he refused to be "roped in" to the debate over whether the U.S. should launch a military strike on Syria.

Bush, whose controversial push for war in Iraq and Afghanistan has been cited by some as a cautionary lesson as the U.S. mulls military engagement in Syria, told Fox News, "The president's got a tough choice to make, and if he decides to use our military, he'll have the greatest military ever backing him up."
